have y'all tried this?!!!!!!

Recently I've been having more sex with my boyfriend and I am always open to trying new things. So this last time we did it, while he was in me I squeezed my vagina muscles together and he said it FELT AMAZING!!!! He even said I love you haha 😝 Our sex before was already amazing and very hot! But this has brought it to a whole other level. I made him cum in 5 minutes which was a win - lose because I didn't get anything out of it but if I can perfect this I can get a win - win lol 😂Get me? Have y'all tried this?
